I know this isn't the kill section, but I digress...

I noticed an 08-09 G8 GXP behind me on the way to work. This road has alternating dual lanes for passing and the G8 got on my bumper while I was in the single lane, so I sped up above the speed limit and he rode my bumper the entire time, so it was clear he wanted some action.

I knew the lane was going to split about a mile down the road, so I slowed back down to around the speed limit of 65mph and then down to about 60 right before the lane split to a dual lane passing zone.

I saw him slowly start to pull around, and then he punched it, so he had a little bit of momentum on me. I put the pedal to the floor and ran the car up to about 100 and locked the converter, man, I'll say this, the billet 6765 with the large .85 a/r hot-side has drastically more top-end power than my old CPT66! I know that roll racing isn't exactly a turbo buick's strong point, but after I locked the converter it was all over but the crying for the G8. LOL. I was walking away pretty strongly after locking the converter. I lifted after I could see the GXP in the rear view mirror (probably around 3 cars back or so) I think I was between 120-130 mph when I lifted, but I'm not exactly sure.

I'm not going to lie though, those things have an LS3 and they are no joke from a roll. I walked away from that car handily, but I walked, didn't run, away. I looked on the internet earlier and those things trap around 109-110 in the 1/4 mile bone-stock.
 
It probably would have been even less safe if I were trying to operate a camera at the same time too. lol

It was on a wide flat dual lane with no other cars around out in the country. I don't think it was incredibly dangerous fwiw.
 
I have a GN and a G8/GXP and have to tell you it is not much of a contest. My GN is way faster but GXP is stock. 3.8 L at 15 lb boost is 7.6 L. Way bigger than 6.2 L! Bet you are running more than 15 psi. Which car would be faster at Autocross or which would stop shorter from 60 mph? GXP....no contest. I love both cars but they are very different.
